【0009】図1は、本発明の実施の形態のガラス基板収納治具20を示している。 [0009] Figure 1 shows a glass substrate storage jig 20 of the embodiment of the present invention. 収納治具20は、ガラス基板10の裏面を支える裏面支持部21と、ガラス基板1 Receiving jig 20 comprises a back supporting portion 21 for supporting the back surface of the glass substrate 10, a glass substrate 1
0の4つの側面を支える上部カバー部22、下部支持部23及び側面支持部24とから構成されている。 Upper cover portion 22 for supporting the four side surfaces of 0, and a lower support 23 and the side supports 24. 更にこれら上部カバー部22、下部支持部23及び側面支持部24は、ガラス基板10の表面周辺を覆うための押え壁25をそれぞれ有している。 In addition, these upper cover portion 22, the lower support portion 23 and the side supports 24 has a retainer wall 25 for covering the surface periphery of the glass substrate 10, respectively. したがって、図2,3に示されるように、ガラス基板10は、裏面支持部21と押え壁25とにより挟持されるようになる。 Accordingly, as shown in FIG. 2, the glass substrate 10 will be sandwiched between the back supporting portion 21 and the pressing wall 25. この押え壁2 This pressing wall 2

上部カバー部22、下部支持部23及び側面支持部24 Upper cover portion 22, the lower support portion 23 and the side supports 24
とは、ボルト等により数個所で締結されている。 And it is fastened in several places by means of a bolt or the like.

【0010】図1に示されたものでは、ガラス基板10 [0010] the one shown in Figure 1, a glass substrate 10
の4辺に渡って押え壁25が設けられているが、実際にはガス流は下流に位置するガラス基板10の下部から裏面に回り込むのが最も多く、図2に示されるように、ガラス基板10の裏面支持部21と、押え壁25を有する下部支持部23のみを設けるだけで、かなりの効果を上げることができるものである。 Most, as shown in FIG. 2, the glass substrate that is pressing wall 25 over the four sides is provided, in practice around to the back side from the bottom of the glass substrate 10 the gas stream is located downstream of the 10 the back support 21 of, simply by providing only the lower support 23 having a pressing wall 25, is capable of raising a considerable effect.

【0011】図3は、押え壁25の別の実施の形態を示すもので、ここでは押え壁25のガラス基板10と接しない方の端部26を流線形にしている。 [0011] Figure 3 shows another embodiment of the pressing wall 25, here it is the end 26 of the person who is not in contact with the glass substrate 10 of the pressing wall 25 streamlines. これは、図2のように押え壁25の該端部26が角部を形成していると、ガス流がこの角部に当って乱流を発生し、押え壁2 This is because if the end portion 26 of the pressing wall 25 as shown in FIG. 2 form a corner, the turbulence generated gas flow hitting this corner, pressing wall 2
5とガラス基板10との隙間から入り込みガラス基板1 5 and the glass substrate 1 enters the gap between the glass substrate 10
0の裏面にいくらか回り込むために、このガス漏れを更に防止するために流線形にしたものである。 To somewhat around to the back side of 0, is obtained by streamlined in order to prevent the gas leakage further. これにより、ガス流はスムーズになり、乱流の発生が押えられる。 Thus, the gas flow becomes smooth, the generation of turbulence is pressed. なお、図3に示されるように下部支持部23の下端部も流線形にすると一層効果が上がる。 Incidentally, more effective, but the lower end of the lower support portion 23 also streamlines as shown in Figure 3.

【0012】図4の(a)は、更に別の実施の形態を示すもので、押え壁25と裏面支持部21と間隔を可変にする構造としている。 [0012] in FIG. 4 (a), but showing still another embodiment has a structure that the pressing wall 25 and the back supporting portion 21 interval variable. これは成膜中の熱によるガラス基板10と収納治具20との熱膨張差から、この間隔が不規則に変形する。 This the difference in thermal expansion between the glass substrate 10 due to heat during the film formation and the storage jig 20, this interval is irregularly deformed. そこでガラス基板10の側面の支持部である上部カバー部22、下部支持部23及び側面支持部24と裏面支持部21との締結を、溶接等の完全固定式から数mm程度ずれて可動する構造とすることで、この変形を吸収しガラスの割れ・欠けを防止するようにしている。 Therefore the upper cover portion 22 is a support portion of the side surface of the glass substrate 10, the fastening of the lower support portion 23 and the side supports 24 and the back support portion 21, is completely fixed offset several mm from the equation movable welding structure with, so as to prevent cracking, chipping of the glass to absorb the deformation.

【0013】図4の(b)は、この1つの実施例を示している。 [0013] in FIG. 4 (b) shows the one embodiment. 下部支持部23には、裏面支持部21に締結するための孔27が穿設される。 The lower support 23, holes 27 for fastening the backing portion 21 is bored. ボルト等の締結具30を挿通する穴31が明けられた円筒状のカラー32が、下部支持部23の孔27内に配置される。 Cylindrical collar 32 having a hole 31 for inserting the fasteners 30 such as bolts are drilled is placed in the hole 27 of the lower support portion 23. 孔27の内径は、カラー32の外径より大きく、カラー32が横方向に数mm程度移動できる大きさとなっている。 The inner diameter of the hole 27 is larger than the outer diameter of the collar 32, is sized to collar 32 can be moved several mm in the transverse direction. カラー32 Color 32
の前後には孔27より大きな径のワッシャー33が配置される。 The front and rear of the washer 33 of larger diameter than the hole 27 is arranged. このような状態で、締結具30をワッシャー3 In this state, the fastener 30 the washer 3
3及びカラー32を挿通し、裏面支持部21のねじ穴に螺合することで裏面支持部21と下部支持部23とが締結される。 3 and inserted through the collar 32, and a back supporting section 21 and the lower support portion 23 is fastened by screwing into the screw hole of the back support portion 21. このような締結個所がガラス基板10の1側辺当り数個所設けられる。 Such fastening points are provided at multiple locations per side edge of the glass substrate 10. なお、下部支持部23の表面からワッシャー33が突出しないように、下部支持部2 Note that, as the washer 33 from the surface of the lower support portion 23 does not protrude, and lower support 2
3の表面にはワッシャー33の収容部が形成されている。 Accommodating portion of the washer 33 is formed on the third surface. この構造により下部支持部23は裏面支持部21に対して横方向に数mm程度移動できる。 Lower support 23 by this structure can be moved several mm transversely to the backing 21. 即ち裏面支持部2 That backing 2
1と押え壁25との間隔が可変にできるものである。 Distance between 1 and the press wall 25 is intended to be variable. 従って、ガラス基板の大型化によって厳しくなった熱膨張差による変形の影響を排除できる。 Therefore, it is possible to eliminate the influence of deformation due to thermal expansion difference became stricter by larger glass substrate.

【0014】前記のように下部支持部23と裏面支持部21との可動構造は、大型ガラス基板10をセットする際に、裏面支持部21と押え壁25とで形成される挿入部位を拡げ、ガラス基板を挿入後に手で押す等によって狭めることで、セット時のガラスの欠け・割れを防止することもできる。 [0014] The movable structure of the lower support portion 23 and the back support 21 as, in setting the large-size glass substrate 10, expanding the insertion site formed by the back supporting portion 21 and the pressing wall 25, by narrowing the like pressing by hand a glass substrate after insertion, it is possible to prevent chipping-cracking of the glass during the setting. なお、下部支持部23以外の上部カバー部22及び側面支持部24にも、前記の裏面支持部2 Also the upper cover portion 22 and the side supports 24 other than the lower support portion 23, the back supporting portion 2
1との可動構造を採用できるものである。 Those that can be employed the movable structure 1.

【0015】図5は更に別の実施の形態を示すもので、 [0015] Figure 5 is intended to show still another embodiment,
裏面支持部21の両面にガラス基板10を配置したものである。 It is obtained by placing the glass substrate 10 on both sides of the back support portion 21. 当然、この場合には押え壁25は、上部カバー部22、下部支持部23及び側面支持部24とも両側に設けられている。 Of course, the pressing wall 25 is in this case, the upper cover portion 22, are provided on both sides both lower support 23 and side support 24. また、前記した押え壁25の端部26 The end portion 26 of the pressing wall 25 described above
の流線形化及び裏面支持部21と支持部22,23,2 Streamlining and back support 21 of the supporting portion 22,23,2
4との可動な締結構造を適宜採用できるものである。 The movable fastening structure between 4 in which can be employed as appropriate. このように裏面支持部の両側を有効に利用することで、省スペースでなおかつ約2倍のガラス基板を収納できる。 By thus effectively utilizing both sides of the back support portion can yet accommodating approximately twice the glass substrate in a space-saving.
なお、本実施の形態では、ガラス基板を垂直に多数並置する場合を例にとって説明しているが、水平に多数並置する場合においても適用可能なものである。 In the present embodiment, it is assumed that the for example when juxtaposing a large number of glass substrates vertically, but also applicable in the case of juxtaposed multiple horizontally. その場合は、原料ガスを反応容器内に横方向から導入して、ガス状副生成物を横方向から排出する等の工夫が必要であろう。 In that case, the raw material gas is introduced laterally into the reaction vessel, may be necessary to devise such discharging the gaseous by-products from the side.

【0016】以上説明したように本発明のCVD,AL [0016] CVD of the present invention as described above, AL
E装置用ガラス基板収納治具においては、ガラス基板の成膜の不具合部を減少できると共に大型のガラス基板であっても割れ・欠けを防止することができ、かつ省スペースで大量のガラス基板を収納できるので、1バッチの処理時間が約12時間程かかるCVD,ALE装置にあっては、その生産効率を格段に改善できるものである。 In the E unit glass substrate storage jig, a large-sized glass substrates together can reduce the trouble of deposition of the glass substrate can also be prevented cracking-chipping, and a large amount of glass substrate in a space-saving since can be stored, the processing time of 1 batch CVD take up about 12 hours, in the ALE apparatus, in which the production efficiency can be significantly improved.
